So guys( im a fan of your you tube channel) .. i enjoyed the etudes, nice study pieces. the explanations were just ok as it was. the last two thirds of most lessons were mostly, in my opinion simply a show of virtuistic skill by the presenter. Yea, Peter is awesome, fun to watch and sure the notation is there to dissect but in all honesty not very informative. Its like going from 5mph to 100mph to be honest. enjoyable but??? Ive gotten more out of your free stuff on you tube. Keep trying tho I enjoy your you tube channel. I've been studying hard in the paint on my own on the Barry Harris stuff. I did see one of your guys do a quick vid on Barry's chromatic scale rules. Free on you tube
